Connect Pixhawk to RealFlight 8

I am trying to import my Pixhawk parameters for an Octocopter hopefully via SITL into RealFlight 8, following this guide (, but I do not have realflight-quad or an octo equivalent within MissionPlanner. Does anyone have this file, or have a suggestion on this task, or can someone suggest an alternative way to simulate my personal drone? Any help would be well appreciated.
